To all whom it may concern:

Be it known that I, Pnnnnvlt. GLASS, of/ Quincy, county of Norfolk, and State of Maseachnsetts, have invented an Improvement in Eyeleting-lvlachines, of which the Yitoliowing description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The present invention relates to an eyeleting-machine, and is embodied in a machine for setti-ngeyelets, rivets, and the like, especially eyelets, the machine being mainly intended for Work on leather'stock, especially shoe-v uppers. I

The invention is shown as embodied in a machine substantially like that shown and described in Patent No. 636,035, granted to mel October 3i, 1899, and relates mainly to certain details of construction and arrangement, as will be hereinafter described.

Figure l is a front elevation of a machine embodying the invention; Fig. 2, a vertical section ofthe same; Fig. 3, a detail in section on the line 003er" Fig. 2; Fig. 4, a similar detail in section on the line of Fig.`2; Fig. 5, a section on planestransverse to that ot' Fig. 2, the upper portieri ot said section being tak'en on a line at the :rear of the punch-trame and thelowerportion being taken on a line farther back and just in front of the feed-operating cam; and Figs. 6, 7, 8, and 9 are enlarged sectional details of the combined punch and setting-tool and the cooperating setting device, together with a portion of the feed-table to illustrate the successive steps in the operation, especially with a view to showing the manner ci inserting and clenching the eyelet.

The machine embodying the invention comprises t-he tubular punch a, (shown as externallyrtapered and provided with the annular clenching-surface cl2) the coperating setting device b, (shown as provided with a springfingerb) and the eyelet-feed chute c, adapted to receive eyelets from the hopper c2 and to be moved into and out of the path ofthe setting device b in the usual Way, so as to successively present the eyelets to the finger b2 prior to the setting operation. The punch a cooperates in the punching operation ,with a suitable anvil or support for the material, the

parte.

ing punching members, the said anvil A being indicated in Fig. 6, in which the punch is shown in the position assumed at the end movement which brings the punch into a position to be met by the setting device also serving to feed the material after the same has been punched. To this end the punch is mounted in a laterally-movable frame a3, (shown as capable of slidingon the guide-rod ai) supported in lugs B, formed in the front part of the trameof the machine. The punch is capable of a reciprocating longitudinal movement within said frame, as will be here inafter described, so as to perform the actual punching operation, but is moved with the frame between successivo punching opera tions, so as to feed the material and copera-te in completing the setting or clenching of the eyelet.

'lo produce the lateral movement of the frame a3, the said frame is connected in accordance With the present invention with an oscillating member d, provided with a radial arm d2, which arm is connected by a universal joint with the pmmh-l`rame a3, so as to compensate for the difference between the curved and rectilinear movements ot the two As herein shown, the said arm d2 is provided with a channel d3, the walls of which engage a sliding block a5, pivotallyconnected with the frame a3, the said block being herein shown as held in position with relation to said frame by means of a screw a, having a rounded head al, whichl constitutes a bearing for the said block. In the oscillation ot' the said member d, therefore, the punch-frame will be laterally reciprocated, it being essential that the said punch-frame should come to rest punch and 'anvil thus constituting coperat-l at one end of its reciprocating movement in such a'position that the punch will be in lino with the setting devicch in order io coperate tongue-or projection d6 from the member d.

order to avoid confusion.

movement of the member d8 is mainly a re! The distance between the lugsd4 is somewhat greater than the thickness of the tongue d, so that by turning one or the other of the screws the position o f the arm relativev to the member d may be determined, as best shown in Fg. A3. v

In the construction shown the lateral movement of the punch is utilized to feed .the material, so as to produce a completely automatic setting operation, the punch first de- "cending to cut the material, then moving aterally to transfer the same to the setting device, and then returning to punch another opening prior to Ithe next setting operation. It is desirable, however, to provide the machine with means for varying the extent of the feed movement in case it is necessary to set part of the eyelets at one distance apart and other eyeletsy in the same line at different distances apart. This is accomplished by varying the lateral or feed movement of the punch, and for-this purpose the member d, which is shown as a sleeve having a bearing on the shaft c, which produces the vertical reciprocating movement of the punch, is provided with a arm d'7, projecting radially from said member and being connected with an actuating member d8, which receives a reciprocating movement from a cam d? on the main shaft C of the machine,which is adapted to be continually rotated during the operation of the machine. The said cam d coperates with engaging surfaces, d10, formed in a frame dm, connected with the member d8, the Said 4member also being provided with fingers or projections d, Fig. 4, constituting a fork ernbracing the shaft C, so as to keep the frame d in proper position with relation to the cam di. These ngers are omitted from Fig. 5 in Thus while the ciprocating movement, said member is free to turn'slightly with relation to the shaft C,

so as to properly follow the movement 'of the ceases stantially the saine as shown in my patent above referred to. The distance to which. the point of connection is shifted by the actuating device is determined by stops d, ad-

justable in suitable lugs lock-nuts (119.'

It is of course' necessary that the punch should always be arrested at the end of its feed movement in such position that it will bedirectly in line with the lower setting device, so as to receive the cyelet therefrom and coperate therewith in the setting operation. To this end the member d8 is connected with the arm (Z7 by 'means of a stud also, ar-

and provided with ranged to engage the walls cfa slot dilin the member di, and the said walls of the said slot clio are curved upon the arc of a circle struck lfrom the axis of the shaft C when the said arm di is in such a position that the punchisdirectly in line with\the lower set. It is obvious, therefore, that no matter to what position the stud e280 is shifted there will be no variation in the position of the punch at this tion of the frame of the machine and providedy with arms c, constituting a forked extremity to engage opposite sides of the cam cT upon the main shaft C. As the said shaft rotates, therefore, the arm el will be swung upon its pivot', thus producing an oscillating moven nient of the shaft c, which is provided with ICO an eccentric es, which coperates with engaging surfaces e9, fixed with relation to the punch and shown as formed in a block or frame ew, which is connected with the punch a. The said surfaces constitute the walls of an 'elongated channel, so that the block el@ is free to travel laterally with relation to the eccentric e8 and to cooperate therewith, regardless of the lateral position of the said block and punch. y

As herein shown, the eccentric e8 does not engage directly with the surfaces e9, but is fitted into an intermediate block cl2, which ts in the said channel and practically constitutes an intermediate eccentric-strap. As the shaft oscillaics, therefore, the punch is vizo oscene carried downward toward the anvil to punch i l, and in order to free the punch from the r il prior to the lateral movement ihc parts are so arranged that the eccentric enough in the oscillation of the the punch down into conta-ct and then slightly up avvayfroin the saine, the c there dwell. in the increment of the shaft c at the end of this time, While the lateral inovementoi the punch-frame immediately begins. This is illustrated in Figs. 6 and 7, Fig. i showing the position of the punch at the completion of the punching operation and iig. 7 the position of the punch after the feed movement has begun.

The slight upward movement of the punch prior to the lateral feed movement separates the same from the anvil or cooperating punching member, so that the lateral movement maybe freely accomplished, it being obvi ous, however, that the parts niay be so timed that these movements may begin almost simultaneously, thereby insuring great rapid ityof operation. lt will be seen, however, from Fig. 6 that at the end of' the punching operation the cutting edge of the punch is on a level with 1the lower surface of the material and that it does not project beyond the surface of the material at all. It is desirable, however, that the punch should be somewhat smaller than the edge of the eyelet which is to be set in order io obviate all liability that the edge of the punch and the edge of the eyelet may come in contact with each other, and thereby injure or destroy one or both, and in any event prevent the proper setting of the eyelet in that particular hole. With the punch smaller than the eyelet, however, and iiush with the surface ofthe material the eyelet instead of entering the opening in the material would come in contact with the uncut material around the punch if the material were allovged to reina-in in the position shown in Fig. G during the setting operation. To insure the proper setting, therefore, and to assist in guiding the eyeiet into the open.- ing, the machine is provided with means for forcing the punch completely through the inaterial until it projects beyond the surface of the saine after the punching operation is corupleted and prior to the setting operation. As herein shown, this is accomplished by prom viding the anvil A or any suitable portion of the feed-table with projecting fingers A2. (Shown on a large scale in Figs. G, 7', 8, and 9.) These fingers project upward beyond the end of the punch, one at each side thereof, as

the raidl punch travels laterally .from the position shovifn in Fig. 6 to the position shown in Figs. 8 and 9. The material carried along by the punch, therefore, will come in contact with the upper surfaces of the lingers A2 and willv be forced, upward onto the punch, as shown in Fig. 7, so that when the said punch is inthe position to coperate with the setting device it will project wholly through the mau eT boing so shaped that- "Iii terial and beyond the lower surface of the saine. This best shovvn in Fig. 8, in which it will be seen that the pun/ch projects into the eyelet 'il until the edge of the ejelet cngages the iapercd weils of the punch, is

thereby guided into the hole made in the ina terial, which is enlarged sniiiciently to properly receive the eyelet, so that the said eyelet cannot fail tochter and be upset or clenched, as shown in S).

It is obvious that the nicans for forcing the punch through the material after the punching operation may be readily inodiiied, and it is not intended, therefore, to limit the invention to the particular means herein shown and described.

The lower set b is carried by a vertical reci procatin g rod b3, adapted'to be reciprocated by means of a wrist-pin C2 upon 'a disk C3, formed upon the main shaft C. The said Wrist-pin C2 enters an opening in a block b, capable of slidingin a cross-head b5, suitablyv connected with the rod b3, so as to produce a regular reciprocating movement of the setting device i); The said setting device l) is vertically adjustable with relation to the rod b3 by means of a screwthreadcd adjusting member b, which bears against the-end of a shell 57, which in turn engages the end portion of the set Z), the upper portion of said set being engaged'by an annular -or nut bs. In adjusting the set the nut ha is turned to such a position as to determine the proper position oi'v the set, and the adjusting 1nember b is then screwed up until the parts are locked, as will be easily understood by ref-- erence to Fig. 2.

The linger b2 is acted upon by a spring b9, contained in the shell 57. The said. finger,

which is adapted to pick up au `eyelet 'froin tlm ICD.

the chute c in the usual Way,is tapered so as not to come in contact with the edge of the punch and will usualiybe depressed by contact with the piece of leather last punched out of the material.

To retain the lmaterial in position after the setting operation has taken place and prior tothe return movement of the punch, the inachine'is provided with a gripper member f, springpressed against the-eed-tablc or anvil, as shown, andconnected with a. vertically movable rod fi, acled upon by an arin f3, pivoted atf'L and operated by a cani f5 on thefshnit C. The parte are so timed that lthe gripper descends and engages the material' just the feed uioveinent is completed and remains in engagement therewith as 'the punch and setting device move apart. To enable the operator to insert the material. prior to starting the machine, the gripper member is also a Iranged to be acted upon. by a levcrj'f", connected with a suitable treadlc or actuating device. (N ot shown.)

The feed-'chute o may be reciprocated or oscillated in any suitable or usual Way to present the eyelets to the setting device and is herein shown as oscillated by means of a cani a ,t ceses c3, acting on the forked extremity c'l ot an elbow-lever c5, suitably connected. with an oeclllatingcframewhich carries the said eyeletchute and feed-hopper, the construction and arrangement of which need not he further described, since they form no part of the prescnt invention.
